Functional Bodywork
The bodywork has been designed to allow riders to perform at their very best for extended periods of time with the distinctive blue radiator shrouds unique to the Heritage models. Following countless hours of testing and refinements, the large contact points and surfaces in the rider triangle enhance comfort, which in turn helps to reduce fatigue. A flat seat profile allows for unrestricted movement while the blue, high-grip seat cover ensures riders stay firmly in place under hard acceleration.
Airbox
A strong, one-piece airbox with optimised air intake tracts ensure an unrestricted flow of air for maximum power. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race-focused testing have proven the exceptional reliability of the high-quality, Italian-made Brembo hydraulic systems.
